Abstract nouns name things you cannot touch: qualities (freedom, kindness), actions and their results (information, a mistake), states (tiredness), and collectives (the crowd). Romanian builds them with a handful of suffixes, and — this is the useful part — the suffix tells you what the base word was and often what register you are in. A noun in -tate almost always comes from an adjective (the quality of being X). A noun in -ție or -eală almost always comes from a verb (the act or state of X-ing). And while -ție sounds neutral and learned, its near-synonym -eală sounds earthy and colloquial. Learn to read these signals and you can decode — and build — abstract vocabulary you have never seen.
-tate: qualities from adjectives
The suffix -tate is Romanian's direct heir of Latin -tas/-tatem — the same source as English -ty (liberty, cruelty). It attaches to adjectives and yields the abstract quality of being that adjective. All -tate nouns are feminine (o libertate).
| Adjective | Abstract noun | Meaning |
|---|---|---|
| liber (free) | libertate | freedom |
| bun (good) | bunătate | goodness, kindness |
| real (real) | realitate | reality |
| posibil (possible) | posibilitate | possibility |
| sănătos (healthy) | sănătate | health |
A closely related sister suffix, -ețe, also turns adjectives into qualities but with a softer, more native feel: frumos ("beautiful") → frumusețe ("beauty"), bătrân ("old") → bătrânețe ("old age"), tânăr ("young") → tinerețe ("youth"). These are also feminine.
Bunătatea ei nu cunoaște limite — ar da și cămașa de pe ea.
Her kindness knows no bounds — she'd give you the shirt off her back. (bun → bunătate)
Frumusețea peisajului m-a lăsat fără cuvinte.
The beauty of the landscape left me speechless. (frumos → frumusețe)
La bătrânețe, sănătatea devine cea mai mare avere.
In old age, health becomes the greatest fortune. (bătrân → bătrânețe; sănătos → sănătate)
-ție / -țiune: actions and results from verbs
The suffix -ție (older/formal variant -țiune) corresponds to English -tion and names the action or result of a verb. It is the neutral, learned way to nominalize and dominates academic, administrative, and journalistic prose. All are feminine.
| Verb / base | Noun | Meaning |
|---|---|---|
| a informa (inform) | informație | (piece of) information |
| a produce (produce) | producție | production, output |
| a reacționa (react) | reacție | reaction |
| a explica (explain) | explicație | explanation |
| a decide (decide) | decizie | decision |
The -țiune form survives mainly in older texts, legal language, and a few set phrases (o singură soluțiune, cu condițiunea), and sounds (formal / archaic) today; modern Romanian prefers -ție.
Am nevoie de mai multe informații înainte să iau o decizie.
I need more information before I make a decision. (informație, decizie)
Explicația profesorului a fost limpede ca lumina zilei.
The teacher's explanation was crystal clear. (a explica → explicație)
-eală: the colloquial verb-noun
Here is a contrast English does not have. The suffix -eală also turns verbs into abstract nouns of action or state — but where -ție is neutral and learned, -eală is (colloquial), earthy, often tied to bodily or everyday experience. Compare the clinical oboseală (tiredness) you might still use anywhere with the unmistakably casual flavour of words like amețeală (dizziness) or fierbințeală. All are feminine.
| Verb | Noun (-eală) | Meaning |
|---|---|---|
| a obosi (get tired) | oboseală | tiredness |
| a răci (catch cold) | răceală | a cold; coldness |
| a greși (err) | greșeală | mistake |
| a ameți (get dizzy) | amețeală | dizziness |
| a îndoi (doubt/bend) | îndoială | doubt |
Am o oboseală de nu mă mai țin picioarele.
I'm so tired my legs can barely hold me up. (a obosi → oboseală, everyday register)
A fost o greșeală prostească, recunosc.
It was a silly mistake, I admit. (a greși → greșeală)
Mă cuprinse o amețeală bruscă și a trebuit să mă așez.
A sudden dizziness came over me and I had to sit down. (a ameți → amețeală)
-ime: abstract qualities and collectives
The suffix -ime has two related jobs. From adjectives, it forms abstract nouns of dimension or degree: înalt ("tall") → înălțime ("height"), vechi ("old") → vechime ("age, seniority"). From nouns denoting people, it forms collectives — "the body of all the X-people": tânăr → tinerime ("the youth, young people as a group"), mult → mulțime ("crowd, multitude"). All are feminine.
Avionul a urcat la o înălțime de zece mii de metri.
The plane climbed to an altitude of ten thousand metres. (înalt → înălțime)
O mulțime imensă s-a strâns în piață.
A huge crowd gathered in the square. (mult → mulțime, collective)
I se recunoaște vechimea de douăzeci de ani în firmă.
His twenty years of seniority at the company are recognised. (vechi → vechime)
Two more workhorses: -ie and -ură
The suffix -ie builds abstract nouns from adjectives and nouns alike: bogat ("rich") → bogăție ("wealth"), bucuros ("glad") → bucurie ("joy"), prieten ("friend") → prietenie ("friendship"). The suffix -ură typically names the result or product of an action: a arde ("to burn") → arsură ("a burn"), a coase ("to sew") → cusătură ("a seam, stitching"). And -ism, as in English, names doctrines and tendencies (realism, optimism).
Prietenia lor a rezistat la distanță și la timp.
Their friendship survived distance and time. (prieten → prietenie)
Arsura de la sobă încă mă ustură.
The burn from the stove still stings. (a arde → arsură, result)
Why the suffix encodes the base and the register
Romanian's abstract suffixes come from two layers of the language. The Latin-via-French learned layer (-tate, -ție, -ism) entered largely through the 19th-century re-Latinization and modernization of Romanian vocabulary, so these endings feel formal and international — and they cluster on bases that are themselves learned. The inherited and Slavic-influenced popular layer (-eală, -ime, -ie, -ură) grew from everyday speech, so it sounds homier. That is why oboseală and fatigabilitate could in principle name overlapping ideas yet live in completely different rooms of the language. When you meet a new abstract noun, the suffix simultaneously tells you the part of speech of its base and which register you have wandered into.
Common Mistakes
Assuming an English -tion word maps onto a Romanian -ție word identically (false friends):
❌ Am o lecțiune azi. (modern neutral)
Dated — the -țiune form is archaic/formal; modern Romanian: lecție.
✅ Am o lecție azi.
I have a lesson today.
Using the colloquial -eală noun in formal writing:
❌ Raportul menționează o greșeală gravă de calcul. (in a stiff legal text)
In very formal register, prefer eroare: o eroare gravă de calcul.
✅ S-a strecurat o greșeală în calcul.
A mistake slipped into the calculation. (neutral/everyday — fine)
Forgetting that abstract nouns in these suffixes are feminine:
❌ un libertate / acest informație
Incorrect — these are feminine: o libertate, această informație.
✅ o libertate / această informație
a freedom / this information
Mishandling the stem change before -tate / -ețe:
❌ frumosețe / bunetate
Incorrect — the stem shifts: frumusețe, bunătate.
✅ frumusețe / bunătate
beauty / kindness
Using cedilla letters in the suffix:
❌ informaţie / libertaţe
Incorrect spelling — comma-below ț: informație, libertate.
✅ informație / libertate
information / freedom
Key Takeaways
- -tate (and softer -ețe) turns adjectives into qualities: liber → libertate, frumos → frumusețe. Always feminine.
- -ție / -țiune turns verbs into actions/results in a neutral, learned register: a informa → informație (the -țiune form is archaic/formal).
- -eală also turns verbs into action/state nouns but is colloquial and earthy: a obosi → oboseală, a greși → greșeală.
- -ime builds qualities (înalt → înălțime) and collectives (tânăr → tinerime, mulțime).
- -ie, -ură, and -ism round out the toolkit (prietenie, arsură, realism).
- The suffix reveals the base's part of speech and the register at the same time — read it as a clue.

Start learning Romanian→Related Topics
- Word Formation: OverviewB1 — Most Romanian words are BUILT, not memorized one by one: a small stock of productive suffixes (and a few prefixes) generates diminutives, agent nouns, abstract nouns, and adjectives from a Latin/Romance core. The three processes are derivation (heavily suffixing), compounding, and conversion (zero-derivation). Learn roughly twenty suffixes and you unlock hundreds of predictable words — and you start to recognize the historical layers (Latin, Slavic, Turkish, Greek, Hungarian, French/Italian, recent English) that make up the vocabulary.
- Agent and Instrument Nouns (-tor, -ar)B1 — How Romanian builds 'the one who does X' and 'the thing you do X with' from verbs and trades: the dual-purpose -tor/-toare (jucător, tocător), the trade suffix -ar (brutar, fierar), the Turkish-origin -giu, and the international -ist.
- Forming Adjectives (-os, -esc, -bil, -tor, -iu)B1 — Romanian's adjective-building suffixes and what each one means: -os 'full of' (norocos), the relational -esc that doubles as the adverb base -ește (românesc → românește), -bil '-able' (locuibil), the verb-based -tor (folositor), and -iu for colours and shades (auriu).
- Grammatical Gender: The Three GendersA1 — Romanian has masculine, feminine, and a third gender — the neuter — that English speakers and even speakers of other Romance languages have to build from scratch. Masculine nouns take un and pattern with -i plurals; feminine take o and -ă/-e endings; neuter take un in the singular like a masculine but switch to feminine agreement in the plural (un tren nou / două trenuri noi). Gender is what every adjective, numeral, and article must agree with.
